Kansas and an extinct bird share top billing in a new documentary film called “Flock of Dodos: The Evolution-Intelligent Design Circus.”

The 84-minute movie, portions of which were filmed in Lawrence, is slated for upcoming preview screenings at Harvard University and other prestigious venues.

The movie explores the science controversy in Kansas and Dover, Pa., which pitted mainstream scientists against proponents of intelligent design. It focuses on tactics and which side is winning or losing the public relations battle.

Randy Olson, the former Kansas University student, marine biologist and filmmaker behind the documentary, said Tuesday that mainstream science was losing the fight for public opinion because most scientists aren’t adept at public relations.
